Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an earthquake control operation system for elevators, and particularly to inspection and restoration means.

[Conventional technology]

Conventionally, elevator control operations have been carried out either by installing a monitoring panel in a part of the control room that controls the entire building, and by the manager using a changeover switch, or in some cases by using an earthquake detection device. Control operation was carried out automatically in conjunction.

However, if you do not perform an inspection operation after the control operation has been completed, there is a risk of damage to equipment inside the tower, separation of the car or counterweight from the rails, disconnection of the electrical system, etc. is dangerous. Incidentally, although these inspections are to be carried out by elevator maintenance companies, there are no regulations regarding the means of recovery after controlled operation, and in the unlikely event that the building manager , when the earthquake detection device is returned to its original position,
All elevators go into normal operation.

Therefore, there was a very dangerous drawback that normal operation could start without inspection, so it was necessary for an inspector to inspect and confirm the condition of the elevator. As described in Japanese Patent No. 56712, an elevator control operation system is provided in which the elevator cannot be returned to normal operation.

However, if inspectors had to board and inspect each elevator one by one, it would take a lot of time, and during that time, the building's functions would be paralyzed.
Such problems can be resolved by dispatching multiple inspectors, but in the case of a wide-area disaster such as an earthquake, the elevators in that region are out of service due to control operations, and the limited number of maintenance personnel available For example, if a large number of elevators are installed and an operation status monitoring device is installed, eight people in the building can inspect and operate the 1FI elevators instead of maintenance staff, and use the elevator status monitoring device to check multiple elevators at the same time. An elevator equipped with this was proposed in Japanese Patent Application Laid-open No. 117971/1983.

[Problem that the invention seeks to solve]

In order to check the condition of an elevator using the method described in JP-A-56-117971, it is necessary to use a large number of monitoring devices for this purpose. Visual confirmation is the most accurate method, so a special feature is to install a television camera in the elevator hoistway and a monitor in the control room to display the images taken by the television camera. This is proposed by Japanese Patent Publication No. fIB60-132883.

In both cases, the equipment is expensive, especially in the case of the latter.
Since it is expensive, it is not practical to install it in each elevator, and in the case of the former, there is no choice but to install a limited number of devices in order to make the device inexpensive, and this is used to check the condition of the elevator. There remains some anxiety as the damage caused by the earthquake is not expected.

The present invention has been made in view of the above-mentioned problems, and when inspecting elevators installed in parallel, an inspector selectively operates an elevator other than the one he or she is boarding, thereby checking the condition of the elevators. The purpose is to provide a control operation method that allows confirmation.

[Means for solving problems]

The above purpose is to provide a means for detecting the operation of an earthquake detection device;
A selection switch that allows the elevator to be operated selectively from the elevator that an inspector is boarding, and a low-speed operation switching means that switches the selected elevator to an operation circuit that allows the selected elevator to operate at a low speed when the selection switch is operated. This is achieved by providing means for operating the operating device of the elevator selected by the selection switch by operating the operating button for operating the elevator in which the first inspector is boarding.

[Effect]

While the detection means is operating, when the selection switch t of the elevator in which the inspector is riding is operated, a low-speed operation circuit is configured in the selected elevator. After the low-speed operation circuit is configured, when the operator operates the operation button to operate the elevator in which the inspector is boarding, the selected elevator will be activated.
The operating device corresponding to the operation button is activated and the vehicle is operated at low speed. As a result, an inspector can check the condition of the other elevators simply by getting into one of the elevators installed side-by-side, without having to get into each elevator and conduct an inspection operation for two inspections. As a result, inspection work can be carried out quickly and efficiently by human inspectors.1. Restoration after elevator control operation in the event of a wide-area disaster caused by a geological formation can be carried out in a short time by the maintenance company's limited number of maintenance staff.

【Example〕

An embodiment of the present invention will be described below with reference to the drawings. The figure is an operational circuit diagram of the No. 1 elevator, in which a royal elevator is installed side by side in the same hoistway.

E13 is the selection switch 5ELL of elevator No. 1, and when 5E12.5Ei3 is operated, the operation assist relay enables operation of the elevators of No. -, 2-band, and No. 3 elevators. The open contact, E213, is the normally open contact of the operation assist relay that enables the operation of the - machine elevator when machine No. 1 is selected in the two-zone machine elevator. Normally open contact of the operation auxiliary relay that enables the elevator to operate, UB is the copper for ascending operation, DB is the copper for descending operation, E-5TOP is the stop button, K1. Kz is the contact of the detection relay that is energized when the earthquake control operation is completed, Sl is the stop relay, Sll is its normally open contact, Ul is the relay for ascending operation, U11 is its normally open contact, and Dl is for descending operation. The relay, Dll, is its normally open contact, (No, 2) Uz, (No, 3) UJI are the signal lines that energize the two-zone machine and the two-zone machine ascending operation relay, respectively.
(No, 2) Dx, (No, '3) Da are the signal lines that energize the two-band machine and the descending operation relay of the two-band machine, respectively.
No. 2) UB, (No. 3) UB are the two-band machine, signal lines for energizing the ascending operation relay U1 of the first machine from the two-band machine, (No. 2) DBz, (No. 3) DBa. is the signal line that energizes the downward operation relay D1 from the second band unit and unit 3 to unit 1, EQlw EQze EQa is the operating contact of the earthquake sensor, P and N are the operating power supplies, and the connections are as shown above. The two-band machine and the third machine have the same circuit configuration.

Next, the operation of the present invention will be explained.

Now, if the earthquake sensor is activated while elevator No. 3 is in operation, the elevator will stop at the nearest floor, open the door, let one passenger out of the car, and wait until the door is closed. ,
After the earthquake subsided, the condition of the elevator was inspected by a specialist engineer from a maintenance company.

When safe conditions are ensured, the earthquake detector is reset and the elevator returns to normal operation.

When a specialist technician inspects the condition of an elevator, the first thing to do is to
The specialized engineer checks the condition of the elevator machine room, and if there are no abnormalities, the first step is to check the condition of the hoistway and elevator by climbing on top of the car and raising and lowering the elevator. A professional engineer gets on top of the elevator car.

When the maintenance operation switch 0N-CAGE is operated, P-
I for low speed operation by ON・CAGE-OCI-N0 circuit
JRA-0CI is energized and the elevator is switched to the low speed operation circuit (
(not shown). If a specialized engineer is on elevator No. 1 and wants to operate his or her own elevator, he or she can operate selection switch 5EII.

Since the earthquake sensor is working, P-EQz-SEtz

! 11 is energized and its normally open contacts 5E11 and 5E1
2 is closed, when operating copper UB for upward operation,
The circuit of P-υB-Ellx-υt-Dt=S1z-N energizes the upward operation relay U1, and the elevator is operated upward at a low speed.

Next, a method for operating other elevators from elevator No. 1 on which an expert engineer is on board will be explained.

For example, when a professional engineer wants to operate a two-zone machine elevator and operates the 1 selection switch 5E12, P-EQx
-3Etz-E12-3ix-N circuit energizes the operation assistance relay Eat, which connects its normally open contacts E12z, E12z and operation assistance relay contact E128 (not shown) of the low-speed operation relay oC of the two-zone machine operation circuit. do not)
is closed, the low speed operation L/-QC of the two-zone machine becomes P-
E12a-QC-N (not shown) is energized and the two-strip elevator is switched to a low speed operation circuit (not shown). After that, when operating the elevator of the two-zone machine, the specialized engineer should operate the copper UB for upward operation or the copper DB for downward operation of the first machine.For example, if you want to operate the elevator of the two-zone machine , Copper U for upward operation
When B is operated, P-UB-E12t-(NO,2)U
The relay Us for ascending operation of the two-band machine is energized by the circuit z,
The elevator of the two-zone machine is operated upward at low speed. At this time 1
If the selection switch 5EII is returned to its original state, the circuit of the driving assistance relay Ell is opened by the selection switch 5EII, so the driving assistance relay Fil is deenergized, and the normally open contacts Ellz and Ells are opened. Even if the copper UB for ascending operation of Unit No. 1 is operated, P-UB-Ell
The l-Ul-OA-31-N circuit is not formed, and the - elevator will not operate upwards.If you want to operate the two-zone elevator, you can operate the selection switch 5E13 to perform the same operation. The circuit allows the two-zone elevator to be operated at a lower speed than the first elevator, which is manned by a specialist engineer.

Operate all selection switches 5llill and 5E12.5E13.

It is clear that by operating the operating copper UB or DB, all the elevators can be operated at once with a specialized engineer on board.

Moreover, if the stop button E-5TOP is operated to the contact open side, the stop relay 81 will be activated when the low-speed operation relay OC1 is energized after the earthquake operation is completed.

P-E-5TOP- is energized by the circuit of x-QCs-5s-N, and its normally open contact Six is opened.

Even if the selection switch is operated, the operation assist relay is not energized, and therefore the low-speed operation relay OC1 of the other machine is not energized, and its normally open contact oC1 is not closed. The stop relays S of other cars are not energized, and for this reason, the elevators are not allowed to be operated by anyone other than a professional engineer on board the car. The safety of the professional engineers on board can be ensured.

In the present invention, a specialist engineer entered the elevator of the first machine for inspection and explained how to operate the parallel elevator using the operation panel of the first machine, but a specialist engineer entered the elevator of the first machine for inspection. The same applies when you board the vehicle.

According to one embodiment of the present invention, when inspecting and confirming the condition of elevators installed in parallel in the same hoistway, a specialized engineer gets on board to inspect and confirm the condition without getting into each elevator. Since it is now possible to operate other elevators from the elevator, the time required for one inspection and confirmation is extremely shortened.Furthermore, direct visual monitoring can be performed by a professional engineer, so there is no need to use monitoring equipment as in the conventional technology. There is no longer a need to install one, and inspections can now be done inexpensively and reliably.

〔Effect of the invention〕

According to the present invention, the condition of the elevator can be directly confirmed by a professional engineer reliably and in a short time without the need for a special device to monitor the condition of the elevator.

And it can be done cheaply.
